Hope this helps.
cheers, I
/facepalm
I'm a bit grumpy, but do you seriously think people do not know weight matters when climbing?
The whole point is that weight hardly matters on the flats. And for a real clincher: Aerodynamics are in 99.99% of the cases more important unless all you do is a mountain TT day in day out.
What's wrong... is setting the slope to 0.00 and changing the other parameters a little bit beyond your ability?

Thanks
What we used to do prior to owning multiple bikes was use your heavy training wheels all the time then put the light race wheels on race day...the difference felt was significant...
When I had both a training bike (Columbus Max) which I would use most of the time then I'd switch to my race bike (Litespeed Ultimate) on the morning of the race...the feeling was magnificent...
Today I see floggers training on the greatest and lightest both in frame and wheels...any benefit is significantly lost in your psyche because the WW bike just feels like any bike if you ride it ALL the time...

What's wrong.... is reading the thread a litlle bit beyond your ability? Because you might take a good look at the model and notice wind and drafting are lacking from the model and yet we are discussing the paceline in this thread.
Let's cut the snark okay? Your model is not shedding light on the subject at hand and I was grumpy pointing it out.

My built up CAAD9 is around 14.5 lbs. I built a lugged frame last year with columbus spirit. Long and low geometry. Build includes full rival and kcnc bits. Its at 17.5 lbs. Only thing i notice is its not as snappy and stiff like the cannondale. But still doesnt hold me back. Fast group/race training rides i do just as much work. I dont think 3 lbs is enough for me to even notice. No hills in Florida though.

3 lb on a hill with around 180 lb net mass is 1/60. So that makes a 6% grade feel like a 6.1% grade. I really can't feel that level of difference.
I was at a really cool shop in Lucerne where outside a Brit man was telling another Brit (woman) how the "lighter bikes will wear you out a lot less on the climbs". I smiled and moved on.

or.. you dont compete and just enjoy the marvel of technology that today's bike are.. instead of letting you 10k bike sleep in the garage 360 days a year..

That's fine too...you just won't feel the psychological gains...

I felt the difference today! First day back on the winter bike (10kg Canyon Inflite AL) after riding the summer on my 6.8kg Scott CR1SL. I rode a route that I cover frequently this morning & I am slower, heart rate higher (strava doesn't lie). The bike is definitely slower, particularly in acceleration.

How do you find the Inflite? I'm umming and arring over whether to buy one at the moment. The spec is great for the current 9.0s, but I'm a little wary of how the alu frame might ride. Is it harsh? How's the fork?

I definitely feel it even though the difference is only 1.4kg. I think the quality of wheelset makes up a big part of that different feel though.

Two weeks ago I took my old bike (20 year old Reynolds 531 roadie) on a regular route in Melbourne, Australia (Banyule Flats/Eltham/Mt Pleasant Rd) for the first time in over a year and I noticed some differences. Much harder to maintain a high speed over rolling terrain.
On a longer climb at lower speeds, there differences aren't that noticeable.
Took the new light bike out on the same route this week, set PBs! The other difference is the gearing. My old bike's lowest gear is 39/25. My new bike has 34/26. I had to muscle the old bike a lot more on short and sharp climbs > 10%. I took that approach with the new bike (instead of sitting and spinning) and it also improved my speed.
